.DISSOLVING-KEY FOR OXYHYDROGEN LIGHTS.

SPECIFICATION forming part of Letters Patent No. 330,092, dated November 10, 1885.

Application filed March 16, 1885. Serial No. 159,103. (No model.)

To all whom it may concern:

Be it known that I, HENRY J. Bnownn, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Dissolving Key for Oxyhydrogen Lights, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improvedkey for oxyhydrogen lights, which key is to be used for turning gas from one jet to one or more other jets, and producing the so-called dissolving effects, or to be used in any other case in which it may be necessary to transfer the gases.

The invention consists in the combination, with a cook or key body having separate channels for the oxygen and hydrogen, of a va1ve-p1ug in each channel,which valveplugs are connected to operate together.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan View of a double oxyhydrogen light provided with my improved key. Fig. 2 is a plan view of my improved dissolving-key. Fig. 3 is a crosssectional view of the same, taken on the line :0 w of Fig. 2. Fig. 4 is a sectional View of the same, taken at right angles to the plane of the section of Fig. 3. Fig. 5 is an enlarged detailed section through one of the central plugs,showing the aperture of the same connecting with the hydrogen passage.

From the body A of the cook or key the nipples B B and G 0 project, the nipples B and 0 being connected with the tubes leading the gas to one oxyhydrogen-burner, D, and the nipples B and 0 being connected with the tubes leading the gas to the other oxyhydrogen-burner, D The hydrogen is conducted through the pipe E from the tank F into the body A, and the oxygen is conducted from the tank F through the pipe E into the said body. In the middle of the body the two tapering bores G and G are arranged which contain the plugs H and H respectively. The bore G is connected by a channel, I, with a neck, to which the pipe E is coupled, and the bore G is connected by a channel, 1

with a neck, to which the pipe E is coupled, so that the hydrogen can pass into the bore G and the oxygen into the bore G The bores G and G are not connected. Channels J and J 2 connect the nipples B and B with the bore G and channels K and K connect the nipples O and G with the bore G, which channels J J K K can be closed by the plugs L L M M, respectively, and entirely independently of each other. The plugs H and H are hollow, and are provided with apertures, which register with the channels I and I respectively, and with opposite apertures, m, which register with the channels J J or K K, as shown in Figs. 3 and 4. A handlelever, N, is connected with one plugfor instance, H -and is connected by a link, 0, with a lever, P, projecting from the plug H and parallel with the lever N, so that when the lever N is in the position shown in Fig. 1 the oxygen and hydrogen can pass from the bores G G through the channels J J and K K the hydrogen passing through the channels I K K" and the oxygen passing the channels I J J Under no circumstances can the oxygen and hydrogen mix in the body A of the key.

Vhen the lever is swung into the position shown in Fig. 2, the plugs H and E are in such a position that all the oxygen and almost all the hydrogen pass to the lamp D a small quantity of hydrogen passing through the lamp D, so that the flame cannot be extinguished.

W hen the lever N is swung in the position shown in dotted lines in Fig. 1, all the oxygen and almost all the hydrogen are admitted to the lamp D, the oxygen is cut off from the lamp D", and but a very small quantity of the hydrogen passes to the lamp D to keep up the flame.

Having thus described my invention,I claim as new and desire to secure by Letters Patent 1. The co1nbination,with the body of a dissolving cock or key having independentlyarranged three-way passages,of the independent plugs, each having apertures to connect with the passages of the three-way passage which it controls, substantially as and for the purpose set forth.

2. The combination, with the body of a dissolving cook or key having separate channels for the oxygen and hydrogen, of a plug in the oxygen-channel and a separate plug in the hydrogen-channel, and of levers for connecting the plugs to operate together,substantially as herein shown and described.

3. The combination, with the body of a dissolving cock or key having separate channels for the oxygen and hydrogen, of a plug in the oxygen-channel and a separate plug in the hydrogen-channel, a bar projecting from each plug,and a link connecting the said bars, substantially as herein shown and described.

4. In a dissolving cook or key for oxyhy- HENRY J. BROWER.
